JIA (read: 嘉, meaning excellent) is a professional consultancy providing quantity surveying and project management services since 1990. At the heart of our practice is the pursuit of excellence, driven by a team of competent individuals, true to our firm’s name.

JIA has contributed significantly to the success of many construction projects from various sectors of the property industry, with construction cost ranging from S$1 million to S$280 million, locally and around the region.

With about 30 years in the business, our team is led by directors with a wealth of experience — who are dedicated to bring every project from concept to completion, focusing on delivering the best value for our clients.


For every project, you can depend on our directors to always be available for client contact throughout all stages. They are committed to guide the team to achieve the best outcome — managing cost and timeline, and resolving any problems or difficulties along the way.

In line with the above commitment, our team of quantity surveyors are provided with regular in-house training in all aspects of QS practices, empowering their performance through professional guidance and support.
